摘要
利用淠史杭灌区及周边 12 个气象站 1958-2022 年气象观测资料和Penman-Monteith公式计算参考作物蒸腾蒸发量(ET0),采用Mann-Kendall趋势检验、敏感曲线和线性回归等方法分析淠史杭灌区ET0 变化特征及主要气象因子对年ET0 变化的贡献,量化气象因素对其影响.该研究成果对提高农业应对气候变化适应能力和抵御气候灾害能力具有重要意义.
Abstract
Based on the meteorological observation data of Pishihang Irrigation District and its surrounding 12 meteorological stations from 1958 to 2022,using Penman-Monteith formula,the reference crop evaporation and transpiration(ET0)was calculated.The variation characteristics of ET0 and the contribution of main meteorological factors to annual ET0 in Pishihang Irrigation Area were analyzed by means of Mann-Kendall trend test,sensitive curve and linear regression.The results of this study are of great significance to improve the ability of agriculture to adapt to climate change and resist climate disasters.
